Deoxypyrimidine monophosphate bypass therapy for thymidine kinase 2 deficiency

EMBO Molecular Medicine, 2014
Autosomal recessive mutations in the thymidine kinase 2 gene (TK2) cause mitochondrial DNA depletion, multiple deletions, or both due to loss of TK2 enzyme activity and ensuing unbalanced deoxynucleotide triphosphate (dNTP) pools.

Autosomal Recessive Cerebellar Ataxias: Translating Genes to Therapies

Annals of Neurology, EarlyView.
Autosomal recessive cerebellar ataxias are disabling neurodegenerative genetic conditions affecting balance and coordination. Advancements in genomic testing have improved diagnosis, leading to a new focus on the development of targeted precision therapeutics addressing cellular, biochemical, and genetic disease mechanisms with a resulting emphasis on ...

Utilization of exogenous thymidine by Chlamydia psittaci growing in the thymidine kinase-containing and thymidine kinase-deficient L cells [PDF]

Journal of Bacteriology, 1976
The incorporation of [3H]thymidine into the deoxyribonucleic acid (DNA) of Chlamydia psittaci (strain 6BC) growing in thymidine kinase (adenosine 5'-triphosphate-thymidine 5'-phosphotransferase, EC 1.7.1.21)-containing L cells, L(TK+), and thymidine kinase-deficient L cells, LM(TK-), was examined by autoradiography. Label was detected over C.

Prodrug Activation by Cryptosporidium Thymidine Kinase [PDF]

Journal of Biological Chemistry, 2010
Cryptosporidium spp. cause acute gastrointestinal disease that can be fatal for immunocompromised individuals. These protozoan parasites are resistant to conventional antiparasitic chemotherapies and the currently available drugs to treat these infections are largely ineffective.

Interpretation of in vitro concentration‐response data for risk assessment and regulatory decision‐making: Report from the 2022 IWGT quantitative analysis expert working group meeting

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...

Effect of an antiandrogenic H2 receptor antagonist on hepatic regeneration in rats [PDF]

, 1988
Because biochemical 'feminization' of the liver in males is observed with hepatic regeneration and because the hepatic regenerative response in females is greater than that in males, the posibility that antiandrogens might potentiate liver regeneration ...

LSF small molecule inhibitors phenocopy LSF-targeted siRNAs causing mitotic defects and senescence in cancer cells [PDF]

, 2019
The oncogene LSF has been proposed as a novel target with therapeutic potential for multiple cancers. LSF overexpression correlates with poor prognosis for both liver and colorectal cancers, for which there are currently limited therapeutic treatment ...

Passatempo Virus, a Vaccinia Virus Strain, Brazil

Emerging Infectious Diseases, 2005
Passatempo virus was isolated during a zoonotic outbreak. Biologic features and molecular characterization of hemagglutinin, thymidine kinase, and vaccinia growth factor genes suggested a vaccinia virus infection, which strengthens the idea of the ...
